Pleistocene Park is a nature reserve on the Kolyma River south of Chersky in the Sakha Republic, Russia, in northeastern Siberia, where an attempt is being made to recreate the northern subarctic steppe grassland ecosystem that flourished in the area during the last glacial period.
The project is being led by Russian scientist Sergey Zimov, with hopes to back the hypothesis that overhunting, and not climate change, was primarily responsible for the extinction of wildlife and the disappearance of the grasslands at the end of the Pleistocene epoch.
A further aim is to research the climatic effects of the expected changes in the ecosystem. Here the hypothesis is that the change from tundra to grassland will result in a raised ratio of energy emission to energy absorption of the area, leading to less thawing of permafrost and thereby less emission of greenhouse gases.
To study this, large herbivores have been released, and their effect on the local fauna is being monitored. Preliminary results point at the ecologically low-grade tundra biome being converted into a productive grassland biome, and at the energy emission of the area being raised.
If this park has all animal species (like what the goal says) and if people disappeared, what will happen to the park itself?

All of its animals (except the only European bison of the park, who had died due to frostbites) including reindeer, moose, Yakutian horses, muskoxen, plains bison, wood bison, domestic yaks, wild yaks, Altai wapiti, snow sheep, saiga antelopes, Bactrian camels, Siberian roe deer, woolly mammoths, mountain hares, black-capped marmots, arctic ground squirrels, Eurasian lynx, tundra wolves, artcic foxes, red foxes, brown bears, wolverines, and Siberian tigers are thriving very well even without human care.

All of the man-made structures of the park has crumbled.
1,000 years after people
All of the descendants of Pleistocene Park's animals have survived and are flourishing in the grasslands (which is now widespread across Siberia once again like in the Pleistocene period). Many descendants of Pleistocene Park's animals are now part of Siberia's ecosystem.
